A stylized face rendered in SVG using D3.js v5, composed of layered circles and rectangles with animated eyebrows. The code builds the face by appending groups and shapes to a centralized `<svg>` element, positioning elements via translation transforms. D3 transitions animate the eyebrow group by shifting its transform over two seconds, creating a bobbing motion. React integrates the D3 selection and arc API for the mouth path, all within a minimal HTML page.
